Description
The present invention relates to connect the anchor clamps that template is used, this template copline and row arrangement, this template have side floor or template at least on two sides, and particularly hollow template, hollow template especially can center on all sides.Above-mentioned anchor clamps have two jaws, and this jaw is suitable for towards the rotating relative to longitudinal surface of side template of butt joint, and to its while application of force.Above-mentioned anchor clamps also have and drive parts, are used to make above-mentioned jaw to rotate.Wherein each jaw has the control arm angled with it, and this control arm is positioned on that end of leaving bite of jaw, and the control arm of two jaws toward each other.About the zone of two control arms of jaw, jaw is installed in rotation on the carriage.To two control arm application of forces, the point of application moves in company with control arm control assembly together, moves apart lining in the position of leaving the rotating support certain distance, thereby anchor clamps are closed up.
Such anchor clamps are described in German patent DE-8814208U and European patent EP-0369197B1, particularly in the result who has obtained aspect the simplification of operation feeling quite pleased, but also can produce required clamping force effectively.In these referenced patent, driver part is a kind of eccentric part with drive rod, and when it rotated, the pivot center of eccentric part can also move perpendicular to the direction of lining.When this eccentric part rotates, its tumbler and rotation
The displacement of supporting makes two control arms produce corresponding displacement simultaneously, and this control arm meshes with eccentric part in the zone of this revolving part or rotating support.Control arm moves apart rotatablely moving of lining makes jaw rotate to side template to be connected simultaneously.This is the very simple anchor clamps of a kind of operation.
If may be subjected to excessive clamping force yet operate incorrect, to be connected side template.If two side floors to be connected have a liner that is placed between them, and the user still makes eccentric part rotate, just this situation can occur always.In addition, according to the anchor clamps of rotated position, the user does not see that drive rod is in clamped position, and these anchor clamps can rotate 180 ° of angles around a horizontal axis.
German patent DE-4236070A1 discloses a kind of anchor clamps that connect the template of template side, and these anchor clamps are because its general arrangement is more suitable for connecting the template with intimate plane floor.Angulation not between jaw and the control arm.In addition, the application point of the adjusting parts of wedgewise is positioned at the prolongation of jaw itself.It is very big to be used for the total size of anchor clamps that hollow side template is tightened together because anchor clamps must two of two jaws every the application of forces on the far point of application, on the other hand, anchor clamps must be fixed on jaw in the anchor clamps cover.If anchor clamps are to do to connect open floor, then the length of anchor clamps cover is necessarily quite long, this make wedge also corresponding lengthening.Like this, a wedge may no longer guarantee to rotate two jaws with enough big power.
German utility model NO.8009045 disclose a kind of connect and row arrangement the device used of template with different qualities, i.e. bolt, lateral shuttle moves this bolt owing to be subjected to thrust and simultaneously to the junction plate application of force of two template sides.This thrust or applied by horizontal pin by the eccentric part that is contained on this bolt, perhaps the screw thread with bolt applies.Therefore because this device is not anchor clamps, not to the side template of the butt joint pivoted jaw of the application of force simultaneously.
Therefore the purpose of this invention is to provide the sort of anchor clamps that a kind of beginning is mentioned, wherein preserved this advantage, it is the point of application that angled control arm forms driver part, and between these point of applications, do not have at interval, or only need very little interval, and jaw and the side template that clamped by jaw can not be subjected to excessive stress owing to excessive clamping force, and the operation of anchor clamps is also easy.
For beginning described have jaw and with this anchor clamps of the angled control arm of jaw, reached purpose of the present invention, its reason is, control arm is a wedge, the use location of this wedge between the point of application on the control arm and side template, make wedge with its dorsad the lozenges of lining to the point of application application of force; When wedge vertically moves, wedge can utilize its lozenges that suitably increases width gradually to close up anchor clamps, the point of application of wedge is configured on those ends away from two jaw rotating supports of control arm, and forms the point of application in identical position, constitutes in conjunction with the point of application; The end of control arm interconnects rotationally, and this end has unsteady play, connector constitute wedge in conjunction with the point of application.
This device of wedge commonly used applies fastening force or clamping force in form technology, and this can reach very big operating flexibility.Because wedge acts on the point on the control arm of two jaws, thus can very equably and can be applied on two jaws by driving the power that wedge produces with indicating, even it is very big to clamp the gap of the jaw that hollow side template uses.In addition, people are easy to also see whether wedge has been driven to the end, promptly can be easy to check clamped position.Assemble also very simple because as long as just can start and make anchor clamps to close up with hammering a blow into shape.Unclamping clip also is like this.
Therefore produced a kind of anchor clamps, this anchor clamps had both kept producing the advantage of closing up motion with wedge, had overcome shortcoming again.Also avoided simultaneously closing up the danger that anchor clamps take place with eccentric part.
Below this point also be particularly advantageous, promptly the point of application of the driver part of wedge form is configured in those ends of leaving two jaw rotating supports of control arm, particularly forms the point of application at same position, constitutes the point of application of combination.Therefore needn't be as the wedge of driver part to some different some application of forces, and its power only acts on the position, and be sent on two drive points of two jaws, thereby make two jaws carry out well-proportioned motion.Thereby the Support of wedge also needn't tilted configuration with respect to the line of two rotating supports of jaw, and according to the anchor clamps of German patent DE-4236070A1, this is essential, because the interval of drive point is big, and reduces at the width of this direction wedge.
Because the end of control arm is connected mutually rotationally, have unsteady play, and connector constitutes the point of application of wedge, so with very simple mode obtained wedge in conjunction with the point of application.Wedge can move parts at an ad-hoc location, and two control arms are rotated simultaneously, moves apart template, thereby jaw is rotated to side template to be connected.Carry out rotational motion with two jaws of a hammer blow on the wide end of wedge just can start and make, and the application of force is very even.Also can utilize the number of hammering more or less to choose at random the size of clamping force.Because be not to rotate eccentric part with lever, can add long lever, make active force very big, so can not produce undue clamping force.In addition, according to wedge and its angle of slope, can pre-determine clamping force with the suitable degree of accuracy.The play that connects in the zone of two control arms can make control arm carry out little rotational motion along arc, and when wedge increased the effect of connector, connector itself then outwards moved more or less in the direction perpendicular to lining.
If it is connector is made the form of connecting pin, particularly suitable.This is the simplest a kind of parts that are suitable for wedge engagement.
Simple especially a kind of solution is on the structure, makes the end of control arm overlapping, and makes connector or connecting pin cross its overlay region.Thus, the rotation of a control arm must cause the corresponding rotation of another control arm, has reached the jaw that requires in simple mode and has rotated synchronously, promptly in the opposite direction rotates to side template to be connected.
This moving that control arm is rotated do not need excessive play, best mode is, if released position at anchor clamps, then the point of application is configured on the line of two rotating supports, or near the configuration of this line and dispose the side towards template of above-mentioned line, if at clamped position then be configured in the lining dorsad of two rotating support lines of above-mentioned connection or a side of template.According to this configuration, the fundamental component of control arm rotational motion is almost perpendicular to lining, line or above-mentioned plane, and is in substantially parallel relationship to the component motion minimum of lining, on this line or the component motion on the plane even be zero.The corresponding play in conjunction with point of application place of the driver part of above-mentioned control arm junction one wedge form can correspondingly reduce.
For the clamping force that is produced by wedge can effectively pass on the anchor clamps, the bearing of supporting wedge towards the opposed surface of lining also coordinated with this point of application position spaced apart, and the gap between the bearing and the wedge point of application can increase owing to insert wedge in the point of application zone of wedge that can be on control arm.The lozenges that also can imagine wedge is pressed against on the point of application, and its opposing face then directly is pressed against on the template of side.But this will produce the friction with the side template, and this is undesirable, because this will produce scratch frequently on the template of side.Therefore the bearing that supports the wedge opposing face is contained in the chuck body better.
The wedge bearing can be installed on the carriage, and this carriage is hollow, or has U-shaped cross-section, and the rotating support of jaw is provided.Because this carriage is essential for rotating support, do not have hell and high water so install the bearing of wedge opposing face additional.
As an example, the carriage with U-shaped cross-section has a gusset piece in its side towards template, and this gusset piece connects two supporting legs of U-shaped and forms or bearing support.Another advantage that this gusset piece has is the retainer that can be used as side to be connected template, and when it is quite smooth and smooth, can be used to collimate template when clamping template.In addition, gusset piece can make anchor clamps stable substantially as a whole, and can be as the bearing of bearing or carrier band wedge opposing face.
Considerable another development of the present invention and advantage may be the opposing face of wedge, the lozenges of this opposing face and wedge is opposite, in the face of lining, be pressed against on the rotating support of jaw movably and/or be pressed against on the bearing, play guiding and supporting role.
The opposing face of wedge only is pressed against just may be enough on the rotating support, and the latter forms bearing simultaneously.Can form good guiding in this way on the very big a part of length of wedge, because these supportings of jaw are each other at a distance of quite far away, the twice that its spacing approximates the length of a control arm deducts half with another control arm overlaid length.But best configuration is that the opposing face of wedge not only is supported on the bearing but also is supported on the rotating support.This causes better guiding, also causes transmitting better simultaneously the active force of wedge, particularly in clamping device.
Another is that with the important development that itself is worth protection wedge is crooked the present invention on plane of rotation, be to wind the arc that the axis perpendicular to the imagination on above-mentioned plane forms, and the inner surface of flexure plane is pressed against on the drive point of control arm.Flexure plane by wedge can reach, and the rotating support of jaw and the place of being rotationally connected of two control arms is configured on the common sides or on the straight line basically, or is separated by very near with this straight line.Even wedge increases from its narrow end to its wider end width, even wedge can make its surface move apart lining to preferably in conjunction with the point of application application of force, but also be directed between them, still keeping the relation of this coplane or conllinear through this rotating support in a side of the lining dorsad of jaw rotating support.
The wedge external surface farther from the center of curvature can mesh with rotating support and/or bearing.
The positive camber of wedge is quite smooth arc continuously, particularly circular arc.This causes when wedge moves, and it can be reposefully along corresponding guide, and preferably two rotating supports and bearing slide.
Dorsad on the face of lining and on the narrow end in wedge shape, wedge has one to be limited in retainer or the protuberance that anchor clamps released position wedge shape device moves, and makes to make wedge keep motionless when anchor clamps are in the released position in wedge.Therefore wedge can be kept motionlessly on anchor clamps, and when using anchor clamps, the operator does not need earlier wedge to be put into initial position, because wedge is in initial position at the very start.
Protuberance cooperates the motion of unclamping that can limit wedge with transverse bolt as the point of application, and still, even in the released position, wedge also is pressed on two rotating supports.In fact, in the released position, wedge also can be crossed the rotating support that is positioned at the narrow end regions of wedge.The above-mentioned wedge in the released position the measure on this rotating support of also being pressed in has increased that wedge is pushed into and the guidance quality of wedge when making jaw enter its restraint location.In a word, improved the guidance quality of wedge, and no matter its bending how.
Simultaneously, this bending of guide provides basic general advantage, and promptly the absolute growth of wedge is quite long, but wedge leniently holds total size of narrow end but quite little.Therefore wedge does not protrude from template or side junction plate to be connected in side direction.Perhaps protrude insignificantly.In order to hit wedge with hammer, wedge itself for example can be easy to approaching in the template zone, more approaching easily than the orthoscopic wedge of routine.
In the side of wedge towards the point of application, wedge has steeper slope on the length that its part of leaving the released position moves, and carries out the transition to the slope that relaxes then.Can fix on such position from the crossover position to slow slope suddenly, in this position, jaw with after the groove of side template or formation it on contacts soon or when beginning to be in contact with it, wedge ability contacts with drive point.Form on one section wedge than steep slope or make width have bigger increase can make jaw before clamping fully accelerate the clamping campaign of jaw on that part of rotation path of process.For anchor clamps can be clipped in easily and the side floor (template) that may still have several millimeters gaps therebetween of row arrangement on, especially be clipped on the groove of the floor of its back, this path is essential.One reaches this position when jaw, and the slope that relaxes just makes the application of force become mild and constant, and can also keep the corresponding clamped position that reached automatically.If the direction that wedge is extended at it broadens with such angle, broaden with such angle in anchor clamps that zone at least in the clamped position effect, make wedge in clamped position locking certainly, then proper.In this position,, then proper if two ends of wedge approximately are positioned at a plane that is parallel to lining.Because wedge is arc preferably, so its end is approximately protruded far equally, for the plane that forms by the side floor or by the carriage of anchor clamps, protrusion is minimum.
The length of curved wedge part, as the radius of curvature of the external surface on wedge surface with can select to such an extent that make the leading section that two wedge faces with the wedge projection that unclamps intersect almost be parallel to lining by the spacing of the rotating support of wedge bridge joint.The advantage of making is like this, and when the beginning clamping device, the user can be in the face of the front end face of wedge, so that squeeze into wedge with hammer.Therefore the leading section of the wedge of being hit by hammer is approaching easily from the outside, until finish clamp operation, has improved the flexibility of chucking operation like this.Because in clamping (closing up) position of anchor clamps, the narrow end of wedge is protruded far equally at the opposition side of anchor clamps, so clout or several reverse motions that just can finish unclamp operation down easily with hammer.
The anchor clamps that are used to connect the template with side floor or side template are provided in a word, and these anchor clamps are fit to existing template, can not produce hell and high water during use, and this anchor clamps biggest advantage is that clamping force can not reduce.Anchor clamps can be contained on the template soon, and according to the position of wedge, the user can visually see, and whether anchor clamps have clamped securely and the time of clamping.Fixture operation is simple, is enough to make it to close up and opens once hammer or a few hammer because only need.
Describe the exemplary embodiment of the present invention with reference to the accompanying drawings in detail, part is a schematic diagram in the accompanying drawings.
Fig. 1 is the plan view of anchor clamps of the present invention, and the anchor clamps that illustrate are in deployed position, is used on the hollow template of two butt joints that are clipped in two copline template sides, only partly template is shown among the figure, represents with chain-dotted line;
Fig. 2 is the rear elevation of anchor clamps shown in Figure 1, still is in deployed position;
Fig. 3 is the plan view corresponding to Fig. 1 anchor clamps, but anchor clamps are closed up and clamp;
Fig. 4 is the rear elevation that closes up anchor clamps of Fig. 3.
Anchor clamps are generally designated by numeral 1, and are used to connect the template of two coplines and row arrangement, and this template has side template 2 on the opposite flank, are hollow template in illustrative embodiment, and this hollow template can suitably center on all sides.These hollow templates are connected with lining 3 in Fig. 1 and Fig. 3, represent with chain-dotted line.
Can see that in Fig. 1 and 3 control assembly is one and is configured in the point of application on the control arm 5 and the wedge 9 between the side template 2 that the lozenges 9a of lining 3 can be directly or indirectly to control arm 5 application of forces and the point of application application of force to forming at this place dorsad.When vertically moving wedge 9, the wedge 9 that width suitably increases just makes anchor clamps 1 close up.Comparison diagram 1 and Fig. 3 can know and see, when anchor clamps open, the little width segments of wedge is between the corresponding point of application on side template 2 and the control arm 5, and when anchor clamps during by shown in Figure 3 closing up, then the wider portion of wedge 9 is arranged in this space, be that the mobile of wedge 9 makes the point of application on the control arm 5 move apart side template 2, thereby jaw 4 is rotated toward each other, thereby also rotate towards the outer longitudinal face 2a of side template 2.When anchor clamps 1 closed up, the point of application of wedge 9 mainly moved apart template, thereby also moved apart side template 2 and lining 3.
The point of application of the driver part of wedge-shaped member 9 forms is positioned on the end away from those control arms 5 of the rotating support 7 of two jaws 4.In illustrative embodiment, the point of application is at same position, or the combined formation of the point of application is in conjunction with the point of application.The end of control arm 5 is connected to each other together rotationally, and this end has unsteady play, also has the connector of usefulness for this purpose on this end, in illustrative embodiment, be connecting pin 10, this connecting pin crosses plane of rotation, constitute wedge 9 in conjunction with the point of application.In Fig. 2 and Fig. 4, illustrate especially how wedge 9 is pressed against on this connecting pin 10 and how the end 11 of control arm 5 overlaps on a part of length of wedge 9, thereby how to handle this control arm 5.Because to two control arms 5 only in conjunction with forming a point of application, so the displacement that is produced by wedge 9 can be transformed to the rotational motion of two jaws 4 exactly.
For control arm 5 being engaged on the wedge 9 and, and the supporting of this connecting pin can be started, should make the end 11 of control arm 5 overlapping and cross this overlapping region with connecting pin 10 in the location guide wedge 9 of the connecting pin 10 that contains the point of application.Drive wedge-shaped member 9, make this connecting pin 10 move apart lining 3 and side template 2, jaw 4 is just rotated by its control arm 5 thus as mentioned above.
Although each control arm 5 forms an arc when rotating, this arc is opposite with the arcuate directions that another arm rotates formation, but should take measures to make connecting pin 10 can be parallel to displacement, and move apart side template 2 and lining 3, and have minimum play with respect to control arm 5.This measure is, in the position that anchor clamps unclamp, make the point of application on the connecting pin 10 near the line of two rotating supports 7 and be positioned at the side towards template of above-mentioned line, and, then make the point of application be positioned at the lining dorsad 3 of above-mentioned line and a side of template at clamped position.Not shown this line in Fig. 1 and Fig. 3, but clearly, according to Fig. 1, connecting pin 10 is positioned at a side of such imagination line, and according to Fig. 3, then is positioned at the opposite side of this line.People can also see, the center of this connecting pin 10 in each case with this line at a distance of same distance.Therefore utilize the circular intersection region that forms by control arm 5 rotations to produce big as far as possible component motion, and produce as far as possible little component motion in the direction that is being parallel to it in direction perpendicular to lining 3.
The bearing 12 of wedge 9 is positioned at the point of application zone of wedge 9 and separated by a distance with this point, and the opposing face 9b towards lining 3 of this wedge is supported by this bearing 12.Therefore, when wedge 9 was driven inward or inserts, wedge was just by bearing 12 supporting, thus its width that increases gradually just to order about the point of application in a manner described be that connecting pin 10 in the illustrative embodiments moves.It is big that distance between the point of application of bearing 12 and wedge 9 can become owing to insert wedge 9, i.e. the motion of wedge 9 converts the rotational motion of control arm 5 in very simple mode, so also convert the rotational motion of jaw 4 to.Bearing 12 helps wedge 9 is produced constant support, and can stand the wearing and tearing that the motion owing to wedge 9 produces.As shown in figs. 1 and 3, hollow or provide the rotating support 7 of jaw 4 and the bearing 12 of supporting wedge 9 for the carriage 6 in U-shaped cross section.The carriage 6 that is roughly the U-shaped cross section has the junction plate 6b that connects U font both wings 6a in its side towards template 3.This junction plate 6b itself is a bearing, the bearing 12 in its supporting illustrative embodiments.The thickness of this bearing 12 can select be well suited for the supporting wedge 9.
A kind of cross plane of rotation and be parallel to the wedge 9 of side template 2 motion also can be to the point of application application of force of wedge, this possible really.Yet be necessary for wedge in this case a mounting that suitably tilts is provided.But think that in illustrative embodiment wedge 9 best modes are to move in the plane that jaw 4 and control arm 5 rotates, and the lozenges 9a of wedge 9 and its opposing face 9b configuration that meets at right angles.Therefore transverse bolt 8 and connecting pin 10 also meet at right angles with the plane of wedge 9 motions.Thereby the lozenges 9a of wedge 9 can be pressed against on connecting pin 10 and the transverse bolt 8 with its opposing face 9b.
In fact according to Fig. 1 and Fig. 3, it is also anticipated that the opposing face 9b towards lining 3 relative with lozenges 9a is pressed against on the rotating support 7 (transverse bolt 8) movably and on the bearing 12, plays a part guiding or supporting.
Wedge 9 is bent around an axis of imaginaries perpendicular to above-mentioned plane of rotation on plane of rotation.Above-mentioned curved inner surface is lozenges 9a, it is pressed against on the point of application of connecting pin 10, and pass through this point to control arm 5 application of forces, this method can make wedge 9 be pressed against on the various points and carry out it and clamp action, neither produce heavy structure, but also allow connecting pin 10 to be configured in a manner described near the line of two rotating supports 7.Though in the released position, compare more close bearing 12 with the line at two rotating supports 7 or its center as the connecting pin 10 of application of force binding site, wedge 9 curved exterior surface, promptly opposed surface 9b is still to rotating support 7 or the transverse bolt 8 and bearing 12 application of forces.If wedge is straight, the various contact points of wedge 9 can not connect in such a way.But the curved wedge 9 of Fig. 1 and Fig. 3 can satisfy all these requirements, therefore can save the space, and configuration rationally.
On the lozenges 9a of lining 3 dorsad, at narrow tapered end place, wedge 9 has the retainer or the protuberance 13 that limit this wedge motion during unclamping, even make that anchor clamps 1 are in the released position, anchor clamps 1 also keep wedge 9 motionless, as shown in Figure 1.Protuberance 13 with as connecting pin 10 engagement limits of the point of application wedge 9 unclamp mobilely, still, even in the position of unclamping, wedge 9 also leans against on two rotating supports 7 (transverse bolt 8).Even therefore when beginning to clamp motion, the narrow end of wedge 9 also can be by transverse bolt 8 guiding of corresponding rotating support 7.
The length of curved wedge part 9, as the radius of curvature of the inner surface of lozenges 9a and by the spacing of two rotating supports 7 of wedge 9 bridge joints can select when wedge is unclamped, its front end 16 is roughly parallel to lining 3, and this front end 16 intersects with protrusion two wedge surfaces partly of wedge 9.Therefore in the time will clamping motion, the operator can directly hit the surface that be positioned at his front with a hammer, i.e. this leading section 16, therefore when clamping device 1, the operator have one be easy near and position easily.
Provide a kind of by constitute simple to operate of fewer parts and the anchor clamps 1 that efficient is high in a word, these anchor clamps can be clamped hollow side template, and can check whether these anchor clamps have really clamped, and the position of wedge 9 is easy to show this situation.Because can not increase clamping force with modes such as elongation levers, be subjected to excessive stresses so in fact can eliminate Side shuttering 2.
